Treatment of chronic chalazion and hordeolum with botulinum toxin
View Patent ↗Chalazia and hordeola are the most common lesions occurring in the human eyelid, and often recurrences are managed by surgical intervention to remove fatty inclusions within the lid with associated inflammatory reaction. The present invention provides non-surgical methods of treating chalazia, hordeola and cutaneous infections comprising the administration of compositions comprising botulinum toxin. The present invention provides methods that effectively block meibum secretion from the meibomian glands, reduce sebaceous bacterial culture media on skin, and sebaceous secretion from the glands of Zeis. Decreased production of meibum and associated fatty substances resulting from the methods of the present invention, decrease gland blockage and tissue inspissations, resulting in reduced recurrence of chalazia, hordeola and related inflammatory reactions and lesions.
1. A method of treating chalazion, comprising the step of administering a therapeutically effective amount of a composition comprising botulinum toxin and a human serum albumin to a subject suffering from chalazion, wherein the composition reduces secretion from the meibomian glands and wherein the human serum albumin is present in an amount between 550 and 550,000 μg human serum albumin agent per 100 LD 50 units botulinum toxin.
2. The method of claim 1 , wherein the composition is administered by injection into the eyelid or conjunctiva.
3. The method of claim 1 , wherein there are at least two injection sites.
4. The method of claim 1 , wherein the composition is administered at a dose between 0.5 and 50,000 mouse LD 50 units of botulinum toxin.
5. The method of claim 4 , wherein the composition is administered by injection into the eyelid or conjunctiva.
6. The method of claim 1 , wherein the botulinum toxin is immunotype A, B, C, D, E, F, or G.
7. The method of claim 6 , wherein the composition is administered by injection into the eyelid or conjunctiva.
8. The method of claim 6 , wherein the composition is administered at a dose between 0.5 and 50,000 mouse LD 50 units of botulinum toxin.
9. The method of claim 8 , wherein the composition is administered by injection into the eyelid or conjunctiva.
10. A method of treating hordeolum, comprising the step of administering a therapeutically effective amount of a composition comprising botulinum toxin and a human serum albumin to a subject suffering from hordeolum, wherein the composition reduces secretion from the sebaceous glands and wherein the human serum albumin is present in an amount between 550 and 550,000 μg human serum albumin per 100 LD 50 units botulinum toxin.
11. The method of claim 10 , wherein the botulinum toxin is immunotype A, B, C, D, E, F, or G.
12. The method of claim 10 , wherein the composition is administered at a dose between 0.5 and 50,000 mouse LD 50 units of botulinum toxin.
13. The method of claim 10 , wherein the composition is administered by injection into the eyelid or conjunctiva.
14. The method of claim 13 , wherein there are at least two injection sites.
15. A method of treating a bacterial or fungal cutaneous infection, comprising the step of administering a composition comprising botulinum toxin and a human serum albumin to a subject suffering from a bacterial or fungal cutaneous infection in an amount sufficient to reduce secretion from meibomian or sebaceous glands, and reduce bacterial or fungal growth; wherein said administration is by injection and wherein the human serum albumin is present in an amount between 550 and 550,000 μg human serum albumin per 100 LD 50 units botulinum toxin.
16. The method of claim 15 wherein the cutaneous infection is caused by an organism selected from the group consisting of Staphylococcus, Streptococcus, and Moraxella.
17. The method of claim 15 wherein the cutaneous infection is in an area selected from the group consisting of eyelid, scalp, feet, groin, and armpit.
18. The method of claim 15 , wherein the botulinum toxin is immunotype A, B, C, D, E, F, or G.
19. The method of claim 15 , wherein the composition is administered at a dose between 0.5 and 50,000 mouse LD 50 units of botulinum toxin.
20. The method of claim 15 , wherein there are at least two injection sites.
21. A method of reducing a sebaceous secretion on a body surface, comprising the step of administering a therapeutically effective amount of a composition comprising botulinum toxin and a human serum albumin to a subject in need of reduced sebaceous secretion, wherein the composition reduces sebaceous secretion; wherein said administration is by injection and wherein the human serum albumin is present in an amount between 550 and 550,000 μg human serum albumin per 100 LD 50 units botulinum toxin.
22. The method of claim 21 , wherein the composition is administered to an area selected from the group consisting of eyelid, scalp, feet, external ear canal, groin, and armpit.
23. The method of claim 21 , wherein the botulinum toxin is immunotype A, B, C, D, E, F, or G.
24. The method of claim 21 , wherein the composition is administered at a dose between 0.5 and 50,000 mouse LD 50 units of botulinum toxin.
25. The method of claim 21 , wherein there are at least two injection sites.
